There was a story maybe from a couple years ago that one of the fed agencies was caught wiretapping or spying on a judge, it might have been a federal circuit court. And it was a significant enough 'outrage' that all the usual hysterics were deployed to describe the situation.

Why wouldn't you surveil judges though to make sure that they were not in contact with criminals? I got a whole panic vibe from the reaction, like the judge was genuinely on the take and was worried that law enforcement had found out. Probably not an uncommon thing.
